Hello.... long story short. I have been completely dairy and soy free for several months, my 6 month old son is exclusively breastfed. He has had mucus poop all the time since he was born. It got better when I stopped the dairy and soy but didn't go away. He tried some solid foods (homemade squash, avocado, and pear) and his poop got more mucusy. I have tried many many things and now I am trying a probiotic-- Solaray BabyLife (dairy free), and giving it to him directly. He has had it for 5 days now. His poop became extremely mucusy at first, and now has changed to a darker color-- like dark green. It's consistency still isn't great but it isn't filled with mucus. Anyone else have an experience of poop changing after starting a probiotic? We've been to so many doctors and specialists, and no one has helped us. They all say that mucus in poop isn't a concern if he's gaining and looks healthy. An allergist did give him an FPIES diagnosis but I don't understand how he fits into that diagnosis at all.... very frustrating!
